ReactJS Tutorial - 21 - Basics of Form Handling (English)

Handling forms in React involves managing form data, capturing user input, and handling form submission. Here's an overview of how to handle forms in React:

State for Form Data:
Use React state (typically with hooks like useState) to store form data and update it as the user inputs information.
Input Components:
Create input components for each form field (e.g., text input, select dropdown, radio buttons, checkboxes) and bind their values to the corresponding state variables.
Controlled Components:
Make sure your form inputs are "controlled components" by setting their values to the state variables and handling onChange events to update the state.
Handle Form Submission:
Create a function to handle form submission (e.g., onSubmit event of the form element).
Validation:
Implement form validation logic to validate user input (e.g., required fields, valid email format, minimum/maximum length).
Display validation errors to the user and prevent form submission if there are validation errors.
Feedback and Messages:
Provide feedback to the user during form submission (e.g., loading spinner, success message, error message).
Use state variables to manage loading states, success messages, and error messages.
